@snail: I think Jeff reviewing it is a "mistake", not because his opinion is "wrong", but because he obviously doesn't enjoy any of the MMO trappings that are the core of the experience. Same as it would be a "mistake" if I reviewed a sports game because I have no interest in them and would probably find the experience terrible. There's a reason people review games in genres they actually like.
Jeff reviews FPSs and Destiny is as much an FPS as an MMO. And there is no one in the staff that is super excited about MMOs.
